Excavator Slewing Bearings Rotation Problem - RIGBRS Bearing

How To Prolong The Service Life Of Slewing Bearing - Know

In heavy duty applications with frequent rotation, premature failure is a common fate for large diameter (for example, 8"to 10") bearings. In large rotating equipment, such as cranes, excavators, and tunnel boring machine, slewing bearings must simultaneously handle a complex load spectrum that encompasses a variety of combinations of thrust, radial, and tilt moment loads.
